This invention relates toa feed water heater and purifier adapted for use on boils ,ers for causing the removal of impurities contained in the. fresh water fed therein,

thereby preventing said impurities .from being transm'ittedto the boiler and forming.

The full'nature. of this invention be I understood from the 'accompanyingdrawl0 ings and the following description and claims. I V V r Fig. 1 1s a cross sectlon through a locomo-,v .--'t1ve' boiler looking toward the rear thereof taken just forward of the feed watermount- I ing.

' In-thesdrawings therepis shown part of A,

locomotive having a boiler '10 supported in the ;usual manner upon a chassis and spring construction, not shown'hereim-and the driv- .--1ngwheels 11. I "there is a cab hous1ng 12 having windows or-lookouts 13, and. a fire box 14;extending below the boiler, the construction 50f the 10- common type well ilznown and in use. 2

- In applying the feedwater heater and purifier tozthe boiler it is desirable and neces-i sary toso arrange it with respect tothe loco- I motive that it will not interfere with any;

.. of the working partsfofithe locomotive, be out of the way and especially willbe arranged so as not to intercept the View of the operators through ,thefwindows or lookouts 13. To accomplish this the'feedwaterheat er and purifier is constructed aswill be hereafter described, and mounted or installed upon the boiler toward the rear thereof by V Simply cutting a hole 15 i-nvthe bottom ofv 4 said boiler and securing'the various parts thereto by riveting. 7

To form and constructthepurifier so as to be adaptable to this-type ,of boiler,-a; sludge drum 16 is made ofboiler plate, cirf cular in cross section, about 18 inches in:

diameter and 26 inches long, havingfa dished bottom 17 riveted thereto-,-and a collar or plate 18 aboutthe top thereof and eXt ndi'ng radially from saidjdrum' so jas1to form flanges adapted to beriveted to the bottom .23 are mounted on. the inside of said drum At the rear of the boiler of the boiler. The plate 18 surrounds the top ofthedruin' and there is provided a downwardly projecting neck 19 opening into the drum and adapted to register and .com- 1 municatewith the opening 15 ofthe boiler. Extending laterally from each side of the municatingwith saiddrum throughlthe elbows21 and'collars 22. Deflecting members so. as to engage and baflie the water discharged-downwardly through'the pipes 20 and cause .-it to hug the sides of the drum soas not to disturb the contents'thereof.

The pipes 20 extei'idupwardly at an angle 7 .will become freed and precipitate to thebottom of the; drum. At the top of the. pipes 24 which with their connections embrace the bottom and sides of the boiler, there are feed water-pipes 26 which communicate with the water tank and are. controlled by any 35 suitable means, not shownvherein. The feed water pipes project into the precipitating. pipes anddischarge the fresh water through perforated nozzles 27, as shownjin Fig. 2. Comniunicatingwith each side oftheboiler" there are leadpipes 28 for conducting thehot water from the boiler into theprecipitating pipe. In each elbow 25 there is provided a projecting boss having an, opening closed by a plug 37in which a hose or other means .95 may be placed for discharging a strong our rentv of waterjfor cleaning the pipes and drum. r I

The action" of .thedpurifier is as follows:

The fhot water from the boiler circulates- D through the purifier as indicated by the, ark rows, entering the top'of each precipitating pipe and passing down into. the drumand back' through the bottom of theboiler- This is caused-by the well known laws of gravity and heat, furtheredby the injection into the top of each'precipitating pipe adja I cent the inlet from the boiler, of cold fresh water therebydecreasing the temperature of r the water from the boiler. The cold fresh te' are released from the fresh water and tend toprecipitate to the bottom of the drum. This precipitation is furthereti'eeted by the slow passage down the, longprecilntating pipe, and the disturbance of its stagnation in the drum avoided by the deflecting i and balliingof the incoining water by the plates 23. The Water standing 1n the drum before reenteringthe boiieu through the hole 1:), however. drops its foreign matter so that when it passes into the boiler it substantially pure. Any oil orskunr arising to thesurface of the water might in the trap at the top of the drum, adyacent the lower surface of the boiler, and blown oil therefrom through the blowoti pipe when said pipe is opened by the operation ofthe rod 31. The foreign matter accumulating in the bottom of the drum is discharged through the pipe and nozzle 33 when the valve 1s opened therein by the rod ill, on-

erated by the hand rod35 through the link 36 which extends upwardly to one side of the boiler in a position to be readilyoperated and controlled by the engineer.

It will be seen from the foregoing that a constant circulation of the boiler water is obtained,which is most desirable in steam boilers for producing thegreatestefficiency embodied inthe steam, and this invention,

therefore, embodies in one constructimi a watercirculating device in addition to the feeding and purifying features. l-Iowever, it is not ueeessarytousc two precipitating pipes, as shown herein, asit will be readily understood that any purifier. will operate with one,although two are preferable, bothfor efliciency and uniformity.

The invention claimed is: y

11. A feed water purifier for a locon'iotive boiler, comprising a sludge drum attached forth.

to and opening into the bottom of the boiler, an upright mixing chamber emptying into the sludge drum, a feed Water connection openinginto the top of the mixing chamber and means for leading Water from the boiler into the top of the mixing chamher; the location of said means being heneath the low Water level of the boiler, substantially as set forth.

2. boiler feedwater purifier of the character described in claim; 1 in which the means for leading Water from the boilerito the mixing chamber is located substantially in a vert-ical plane that passes through the sludgedrum, said plane being at right-angles to the major at axis of the boiler, sub stantially as set forth. i t 1 1 3. A boiler feed Water purifier comprising a sludge druniattached to and openinginto the bottom of the boiler, anupright mixing chamber emptying into the sludgeidnum, a

battle plate positioned adjacent the opening through which the fluid fronr the mixing elialnber enters the sludge drum whereby the said fluid is directed against the Wall of the said sludge drum and afiange inside said drum extending downwardly from and surrounding the opening into the'boiler and a blow-off pipe connected to the upper part of the drum for removal of the floating waste matter, substantially as set forth.

4. A boiler feed water PUI'lfiGrKCOIHPllsmg a sludge drum attached to and opening into the bottom of the boiler, an upright mixing chamber emptying into the sludge drum, said mixing chamber discharging into the sludge drum tangentially,l a flange inside said drum surrounding the'open-ing into the boilerwand extending downwardly from saidbottom to a position in the drum relatively free from impuritiesin'the Water, anda blow-elf pipe connected to the upper part of the drum for removal of the floating Waste matter, substantially Inwitness whereof, I have hereunto affixed my signature. 1 i
